Dear listoïdes
I would be very curious to have your ideas about
the following meteorite, here above the story:
In 2002, I have purchased a mix meteorites- earth
stones from a Moroccan dealer during the
Brussels mineral show. 60% of them was
meteorites (many chondrites, one little eucrite,
and some magnetics strange stones, terrestrials
following my desert & meteorite experience)
One of them showed a very strange
lithology. Earth rock or meteorite? My first
impression after cutting was a simple rock from
Sahara
but
a little magnetic attraction on one
side and some cm² of very thick chocolate
alteration on other side (old fusion crust?) asked to more investigations.
The first question: Meteorite or not? has been
resolved in 2006 by prof Jedwab (University of
Brussels) during a quick microprobe
analysis. With lot of hesitation, its a
meteorite, congratulation He said: probably a
very very old weathered chondrite, no
interesting
perhaps achondrite, but my analysis
is not perfect. I found only one little Fe-Ni
flake. I think that was a mud aggregate, but its a meteorite
Other visual submission to prestigious
institutions was blocked during the first
contact: Oh, if its a meteorite, it is so
weathered, no interest to study it
probably a little ordinary chondrite.
Recently, I have submitted a fragment of this
rejected ugly meteorite to a Belgian
laboratory, who studies several meteorites
including Antarctica meteorites from summer 2009-2010 collect.
The first result is fall some days later: The
meteorite is very close to ureilite group, but
there is a little problem. It contains an unusual
part of pure carbon. Analysis continues at this time.
We have searched equivalent meteorites, without
result, except for Almahata Sitta meteorite.
On internet, the following link shows a
electronic photo of Almahata sitta. Photo's are
very similar. Please, compare it with following
electronic pictures of my rejected meteorite.

Each square and reticule corresponds to an
analysis area. Result on request by square if you are interested.
I would be very curious to read you.
